“…Além disso, parte das espécies de lianas apresentam picos de floração e frutificação alternados aos das espécies arbóreas na Floresta Estacional Semidecídua, garantindo a oferta de recursos alimentares à fauna de polinizadores e dispersores em períodos de escassez , Galetti et al1994, Morellato & Leitão-Filho 1996 e também contribuem na formação da complexidade estrutural da floresta, servindo para a movimentação, abrigo e coexistência da fauna arborícola não alada, ao criarem verdadeiras estradas suspensas entre as copas das árvores (Giné 2009, Putz 2009, Melo et al 2011.…”

-(Diversity enhancement of a forest under restoration through direct seeding of lianas). The aim of this study was to analyze the feasibility of direct seeding of liana species in the understory of a restoring forest. Seeds of the species Phanera sp., Macfadyena unguis-cati (L.) A.H. Gentry, and Peltastes peltatus (Vell.) Woodson were submitted to germination tests considering the presence and absence of light and temperature cycle variation. These species were also planted under a canopy of four tree species in a 21-year-old restored forest in Iracemápolis, São Paulo State, Brazil. Macfadyena unguis-cati was the only species presenting a positive photoblastic characteristic, while the two other tested species were not affected by light or temperature cycle. In the understory, Peltastes peltatus did not emerge. In the two other species, seed germination was not influenced by the selected tree species. These results suggest that despite the low rate of emergence, it is possible to enhance the diversity of forest by restoring it through direct seeding of some liana species. Key words: forest restoration, germination, seasonal semideciduous forests, understorey RESUMO -(Enriquecimento de floresta em restauração por meio de semeadura direta de lianas). Este trabalho objetivou verificar a viabilidade da semeadura direta de lianas no sub-bosque de floresta plantada em restauração. Para isso, sementes das espécies Phanera sp., Macfadyena unguis-cati (L.) A.H. Gentry and Peltastes peltatus (Vell.) Woodson, de lianas foram submetidas a testes de germinação com e sem luz, e com e sem alternância de temperatura. Posteriormente, essas espécies foram semeadas sob a copa de quatro espécies arbóreas em uma Floresta Estacional Semidecidual em restauração no Município de Iracemápolis, SP, Brasil. Em laboratório, apenas Macfadyena unguis-cati apresentou característica de fotoblastismo positivo. As outras espécies não tiveram germinação limitada pela ausência de luz e alternância de temperatura. No sub-bosque, Peltastes peltatus não emergiu; as outras duas espécies não tiveram a emergência alterada em função das espécies arbóreas do dossel sob as quais foram semeadas. Esses resultados sugerem que, apesar da baixa taxa de emergência, é possível o enriquecimento de florestas em processo de restauração a partir da semeadura direta de algumas espécies de lianas.

“…Using certain survey techniques has previously led to erroneous species identification, such as for the genera Mazama and Leopardus and the species Herpailurus yagouaroundi (É. Geoffory Saint-Hilare, 1803). Thus for all three survey methods Mazama species were considered as a group, with the presence of either Mazama gouazoubira (Fischer, 1814) or M. americana (Erxleben, 1777) in an area not specified; secondly, the tracks of small species belonging to Leopardus and of H. yagouaroundi were not included, since their track identification is often not completely reliable (BorgeS & ToMáS, 2004); finally, since only Didelphis aurita (Wied-Neuwied, 1826) was considered to occur in forests of the interior of the Park based on an intensive capture program (Melo et al, 2011), all tracks identified as Didelphis were specified as belonging to D. aurita.…”

ABSTRACT. In order to evaluate the efficiency of different mammalian survey methods, we compared traditional sampling techniques (use of camera-traps on roads and artificial trails, track censuses, and direct field visualization) with an alternative sampling design (camera-traps positioned in natural areas such as natural trails and shelters). We conducted the study in a deciduous Atlantic-Forest park in southern Brazil, and additionally compared our results with a previous intensive study carried out in the same area. Our considerably smaller sampling effort (example: 336 trap.day for our camera-traps versus 2,154 trap.day for the earlier study) registered the presence of 85% of the local known species, with camera-traps being 68% efficient. Moreover, shelter camera-traps revealed a different species composition regarding most of other sampling methods. This sampling strategy involving natural forest sites was therefore able to effectively optimize the chances of evaluating species composition in a shorter period, especially with respect to lower-density and cryptic species, as well as to detect species that avoid open, disturbed sites such as roads and man-made forest trails. KEYWORDS.Combined sampling, diversity evaluation, forest interior, trapping effort. RESUMO. Utilização de armadilhas fotográficas em carreiros naturais e abrigos para amostragem de mamíferos da Mata Atlântica.A fim de avaliar a eficiência de vários métodos de levantamento de mamíferos, comparamos as técnicas de amostragem tradicionais (uso de armadilhas fotográficas nas estradas e trilhas artificiais, procura por pegadas, e visualização direta em campo) com um delineamento amostral alternativo (armadilhas fotográficas posicionados em áreas naturais, tais como carreiros naturais e abrigos). Realizamos o estudo em uma floresta estacional decidual no sul do Brasil, e comparamos nossos resultados com um estudo anterior intensivo realizado na mesma área. Nosso esforço amostral consideravelmente menor (exemplo: 336 armadilhas.dia para armadilhas fotográficas contra 2.154 armadilhas.dia no estudo anterior) registrou a presença de 85% das espécies previamente conhecidas para a área, com armadilhas fotográficas tendo 68% de eficiência. Além disso, as armadilhas fotográficas posicionadas em abrigos revelaram uma composição diferente de mamíferos em comparação com a maioria dos outros métodos de amostragem. Esta estratégia de amostragem que envolve locais de floresta natural foi, portanto, capaz de efetivamente otimizar as chances de avaliar a riqueza de espécies em um curto período, especialmente com relação a espécies crípticas e/ou de menor densidade, bem como detectar as espécies que evitam áreas abertas, como estradas e trilhas abertas pelo homem na floresta. PALAVRAS-CHAVE.Combinação de métodos, avaliação da diversidade, interior de floresta, esforço amostral.

“…The park is covered almost entirely by subtropical broadleaf or broadleaf deciduous forest. The mammal fauna of the park consists of carnivores such as Galictis sp., Cerdocyon thous, Nasua nasua, Procyon cancrivorus, Eira barbara, wild cats, herbivorous like deer and tapirs, some species of lagomorphs, primates, didelphimorphia, and xenarthrans, many species of chiropterans and as well as numerous rodents (KASPER et al, 2007;MELO et al, 2011).…”

In the present study, Litomosoides silvai parasitizing Akodon montensis in the southern region of Brazil is reported for the first time. New morphological information is provided for some structures of this nematode species, such as a flattened cephalic extremity, presence of two dorsal cephalic papillae, female tail with a constriction at its tip, "s" shaped vagina, spicules characteristic of the carinii species group and microfilaria tail constricted at the tip. This nematode was found parasitizing the thoracic cavity with a prevalence of 10% (2/20), mean intensity of 4 (6/2), mean abundance of 0.4 (8/20) and range of infection of 2-6 specimens per host, in southern Brazil. This occurrence of L. silvai in A. montensis is a new geographical record for southern Brazil, in the Upper Paraná Atlantic Forest ecoregion of the northwestern region of Rio Grande do Sul, which is part of the Atlantic Forest biome.
